VIP, scientifically known as vasoactive intestinal polypeptide, is a naturally occurring amino compound studied for its interactions with receptor-mediated signaling pathways across multiple biological systems.

Current research examines VIP in experimental models involving cellular communication, immune-associated signaling, smooth muscle regulation, vascular biology, and neuroendocrine processes. Its broad receptor activity makes it a compound of interest for investigating the complex signaling mechanisms involved in cellular homeostasis and coordinated physiological responses.
